The **MHO+53TCG-R** is a specific part number for a high-performance **Crystal Oscillator** (often referred to as a Clock Oscillator). It is manufactured by **MtronPTI**, a company specializing in frequency control and spectrum control solutions. ### 1. Component Overview This component is an integrated circuit that combines a quartz crystal with oscillation circuitry to provide a precise, stable square-wave clock signal for digital circuits. | Feature | Specification | | :--- | :--- | | **Component Type** | Crystal Oscillator (XO) | | **Series** | MHO+ | | **Package Size** | 5.0 x 3.2 mm (SMD) | | **Output Type** | HCMOS / TTL Compatible | | **Standard Frequency Range** | 1.0 MHz to 156.25 MHz (Variable based on specific sub-code) | | **Operating Voltage** | Typically 3.3V (standard for + series) | --- ### 2. Decoding the Part Number The alphanumeric code provides specific details regarding the electrical characteristics and environmental tolerances: * **MHO+**: Represents the product series (5x3.2mm Surface Mount, High stability). * **5**: Indicates the Operating Voltage (typically 5.0V or 3.3V depending on the specific revision, though "+" usually denotes a 3.3V design). * **3**: Represents the Frequency Stability (e.g., ±50ppm or ±25ppm depending on the manufacturer's specific datasheet table). * **T**: Temperature Range (Usually "T" indicates an extended industrial range, such as -40°C to +85°C). * **C**: Output Configuration (HCMOS/TTL). * **G**: RoHS Compliance (Lead-free/Green). * **-R**: Packaging (Tape and Reel). --- ### 3. Pin Configuration (Typical 4-Pin SMD) Standard crystal oscillators in this 5x3.2mm package follow a universal pinout: | Pin Number | Function | Description | | :--- | :--- | :--- | | **1** | E/D or NC | Enable/Disable (Tri-state) or No Connection | | **2** | GND | Ground connection | | **3** | Output | The actual clock signal (Square wave) | | **4** | Vdd | Positive Power Supply | --- ### 4. Typical Applications Because of its small footprint and high stability, the MHO+53TCG-R is commonly found in: * **Networking Gear:** Routers, switches, and modems. * **Industrial Electronics:** PLCs and automation controllers. * **Embedded Systems:** Providing the heartbeat for Microcontrollers (MCUs) and FPGAs. * **Computing:** Peripheral interfaces and data storage devices. ---
